IMPROVEMENT IN OIL-TANKS.

Specification forming part ofLetters Patent N 0. 206,581, dated July 30,1878 application filed May 4, 1878.

To all whom 'it may concern Be it known that we, WILLIAM K0011 andGEORGE KOCH, of Monroe, in the county of Clarion and State ofPennsylvania, have invented a new and valuable Improvement in Oil-Tanks;and we do hereby declare that the following is a full, clear, and exactdescription of the construction and operation of the same, referencebeing had to the annexed drawings, making a part of this specification,and to the letters and figu'res of reference marked thereon.

Figure lot the drawings is a representation of a top view of my improvedtank. Fig. 2 is a vertical section thereof. Figs. 3 and 4 are sectionalviews of the joint, and Fig. 5 is a side view of the tank.

This invention has for its object to devise a tank for storing oil atthe wells, that may be readily taken apart when they are exhausted,transported in a knocked-down condition to another place, and readilyand expeditiously set up in proper state to receive the oil.

The nature of the invention consists in an oil-tank composed of a bottomand two or more metallic stave-sections detachably secured thereto andto each other, as will be hereinafter more fully set forth.

In the annexed drawings, the letter A designates the bottom of myimproved tank, composed of wooden sections united together in anysuitable manner, and prevented from casual separation from each other bya strong metallic hoop, b. This latter may be shrunk on after the mannerof a tire, or applied tightly thereto by means of a clamping device.This bottom is provided with an annular V-shaped groove, a, near itsedge, in which the lower end of the barrel of the tank is seated. Thisbarrel B is composed of two or more sections, 1), having upon theiredges the outwardlybent flanges c, and they are coupled together bymeans of the clamp-plates c at each side of said flanges and theclamp-bolts and nuts 0 e, as shown in Fig. 3 or, as in Fig. 4, they mayoverlap each other, and be coupled together by means of the clamp-plates0, (one inside and the other outside of the tank,) the clampbolts 0, andnuts 0, as before. In either case a packing may be inserted between theflanges or lapped portion of the stave'sections to render themair-tight; or the same result may be attained by calking the seam withoakum.

When the barrel is seated on the bottom with its lower edge in theV-shaped groove a, it is made to form a tight joint therewith by meansof oakum forced into said groove inside of the tank; or the joint may bemade secure by applying plaster-ot paris or other cement in said groove.

Heretofore the tanks for oil-wells have been made of wood, both sidesand bottom put together after the manner of a cask. Coal-oil causes thewood to shrink, and thereby renders the tank leaky, so that the staveshave constantly to be reset. When these wooden tanks are taken to piecesfor removal it is exceedingly difficult to set them up again so as toprevent leakage.

Metal tanks have been used withtheir parts riveted together; but fromthe labor required to cut the rivets, and the impossibility of againputting the parts together so as not to leak, not to mention the cost ofskilled labor,

they have not been made in detachable sections, but only as permanentconstructions, and then only at the shipping-depots.

What I claim as new, and desire to secure by Letters Patent, is-

In a storing-tank for oil-wells, the combination of the bottom A, havingthe hoop b and an annular groove, a, in its plane surface for thereception of the barrel B, provided with sections I), having joinededges 0, the clamp-plates c, and bolts 0 c, substantially as specified.

In testimony that we claim the above wehave hereunto subscribed ournames in the presence of two witnesses.
